-the. carriage shiftedwupon the rails, there will be ind-tendency of the stencil-carrying frame .to overbalance the carriage toward the rear of the machine.

Another feature of the invention is the provision of a simplified bracket, which functions as a supporting means-for a carbon-paper receptacle and carries a stop for .frame 20 and is graspedtoaid in operating limiting the rearward. position of the sten til-carryingv frame when thrown .backout of operation:

further feature embodies a guard device which. isefi'ective to retain the carbonpaper roll'within its receptacle, the arrange-' ment being such, that a roll-may be quickly *and. easily inserted or withdrawn therefrom.v l 5:. .-1

A coil spring 36 encircles the rod and isefiective to cause a roller 37 journaled in a forward extension 38 of a yoke 39 to hold a strip of carbon-paper 37 pressedagainst the platen 13, and a handle 40, associated with the yoke, serves to lift the roller from the platen when so desired. The stencilframe 20 comprisesa pair of arms 41 joined together by a yoke-piece 42 upon a rod 43 disposed at the rear of the machine and extendingparallel with the platen-shaft, the ends of the rodbeing milled flat and securedby suitable screws 44 to extensions 45 -and'46 of the end plates 32 and 38, respectivelya It will be noted that the rod 43 is positioned well in toward the platen, so that when=the stencil-frame is thrown back and stopped, to occupy the position indicated by dotted lines in Figure 1, the center of weight of the framewill be close'to the carriage; Thus,ithere-will be no tendency of overthrowing the carriage toward the' rear of the machlne, such as would occur, ifthe "frame were so constructed as to occupy a -prises-a sheet of metal curved to form an open-ended cylinder, having a slot 48 through which the paper is threaded from agroll of carbon-paper 49. Abracket 50 is-formed at its lower end'with'a boss 51,

' whichis drilled but so as to be received upon comprisesalength'otspring wire 54 fas-' tenedtupon the top of the bracket adja-' the rod 43, and is secured thereto by means of set-screws 52, so that the bracket will be stationary with the rod. A horn-shaped extension ofthe boss'51provides-a stop 53, which lies in the path of movementof the yoke-piece42'of the frame-20 when the latter is thrown back about its pivot, and acts as a'limiting m eansto govern the rearward position of the stencil-frame. The upper end ofzthe bracket is curved and fastened:

to the receptacle 47 by soldering, or in any otherinanner found desirable.

Means are provided for retaining thepaper-roll 49 within the receptacle 47 -.and

cent the receptacle 47 and held to the bracket by means of a screw 55,-so as to provide a pair of fingers 56 and 56'. The fingers 56 and 56 extend from thebracket in' oppo site directions along the back-of the recep tacle, to a point slightly beyond the endso'l' the receptacle where :theyare bentv substan tially at right angles, as-shown inFi gures 3 and 4, and formed with loops 57 to overlie the open ends of the receptacle 47. It'is obvious that a carbon-roll may be inserted or withdrawn from the receptacle by simply moving thefree end of the finger 56v away from the end of the receptacle, as illustrated inFigure 3.

In typing stencil-cards upon an ordinary typewritin machine, it is customary to provide a bac ing for the cards, soas'to prevent thetype blows from injuring the platen. A device of this nature is disclosed in my pending application, Serial No. 708,332,

filed April 23, 1924, and need not be described in'detail in the present application,

as it formsno part ofthe present inven-' tion. The backing consists generally of a sheet of celluloid orTsimilar-material 58 en-' When it is desired to print-upon the back ofthe stencil-cards, the carbon-paper 37 is led through'the slot 48 2 down around the platen, andnundersthe roller37 through a guide 62,and thence upwardly over the top; of the receptacle 47,- ,and, upon operating the handle 22 to release the roller '37- fromthe vpaper', an -unused area of carbon-paper may be fed beneath the card by grasping the free end of the paperv and drawing it aroundthe-platen- :For thepurpose: oflassisting in guiding. the stencil to position around the platen,

provision-may be made of a deflector-plate 63 .mountedbyzfinge'rs 64 upon the type-bar segment illby means of suitable screws 65.

This deflector-plate may be formed of a singlepiece ofsheetnetal, and-is notched out at 66 toprovide clearance for theztype-bars when driving their type through a type guide 67 'and against-the stencil-card 18. The defiector plate is curved forwardly and downwardly so' 'as :to engage the lower por tion of'an inserted stencil-card, and press it'toward theplaten, and thereby assure the stencil being held against the platen at the typing pointv The deflector-plate is. of a length sufficient to extend well over both endsvof the inserted fcard; and it will be noted thatthe majorportion'of the card is in contact with the/curved portion of the tion, the cards may be'moved to or removed from printing position without danger of the .i deflector-plate catching onto the marginsof the cards.'
